Brief update...
Logan is now off his oxygen, out of his incubator, and has been upgraded to a crib. Still has a feeding tube, as the respiratory troubles cause a bit of trouble with the whole suck/swallow/breathe eating thing. (he's got mom's light hair)
Liam is out of his incubator and has been upgraded to a crib, but he's still getting a little O
2 help. No biggie, really. He also still has a feeding tube, same reason as his brother. (and he's got dad's dark hair)

Both boys are getting quite a bit stronger each day, so it should only be a few more days before they get to come home!
